2024publicationDillon, Gregory K.originatorLazarz, Mitchell T.originatorKarau, Eva C.originatorStory, Scott J.originatorPohl, Kelly A.originatorForest Service Research Data ArchiveFort Collins, COpublishermapDigitalThis data publication includes Community Wildfire Risk Reduction Zone rasters, products delivered as part of the Wildfire Risk to Communities project. There are two types of data included: 1) raster spatial data that delineate Community Wildfire Risk Reduction Zones for all populated areas in the continental United States (CONUS), Alaska, and Hawaii; and 2) tabular summaries by communities, counties, tribal areas, and states of wildfire hazard and risk produced as part of the Wildfire Risk to Communities (WRC) project.The Community Wildfire Risk Reduction Zones (CWiRRZ) product is a 30-m raster delineating areas where mitigation activities will be most effective at protecting homes from most types of wildfire. The zones are determined by the spatial coincidence of wildfire likelihood (Burn Probability), and populated areas. There are four Risk Reduction Zones: Minimal Exposure Zone, Indirect Exposure Zone, Direct Exposure Zone, and Wildfire Transmission Zone. However, the CWiRRZ raster can be further deconstructed into ten zones, wherein the Wildfire Transmission Zone is separated into the following surface fuel types: Tree, Shrub, Grass, Agriculture, Non-Vegetated, Water, and Outlying Wildlands (area beyond 2400-m from buildings).Additional methodology documentation is provided with the data publication download. (https://www.fs.usda.gov/rds/archive/Catalog/RDS-2024-0030)Note: Pixel values in this image service have been altered from the original raster dataset due to data requirements in web services. The service is intended primarily for data visualization. Relative values and spatial patterns have been largely preserved in the service, but users are encouraged to download the source data for quantitative analysis.The geospatial data products described and distributed here are part of the USDA Forest Service Wildfire Risk to Communities project. This project was directed by Congress in the 2018 Consolidated Appropriations Act (i.e., 2018 Omnibus Act, H.R. 1625, Section 210: Wildfire Hazard Severity Mapping) to help U.S. communities understand components of their relative wildfire risk profile, the nature and effects of wildfire risk, and actions communities can take to mitigate risk.
These data serve two purposes: 1) provide nationally-consistent spatial data that could be used to summarize hazard and risk to populated areas and take into consideration areas with housing units as well as adjacent areas with wildland fuels; and 2) provide communities with a way to spatially identify where different types of risk mitigation activities are likely to be most effective.Funding for this project provided by USDA Forest Service, Fire and Aviation Management. Funding also provided by USDA Forest Service, Fire Modeling Institute, which is part of the Rocky Mountain Research Station, Fire, Fuel and Smoke Science Program. Work on data development was primarily completed by the USDA Forest Service, Fire Modeling Institute (FMI). Some salary was provided by FMI through an ORISE agreement under the U.S. Department of Energy (DE-SC0014664).

4 Class CWiRRZ:

4. Wildfire Transmission ZoneAll pixels that are part of the land and water of the United States have valid non-negative values.The Wildfire Risk to Communities (WRC) datasets are based on wildfire simulation modeling. Given the relatively short time available for analysis and production of the WRC datasets, the methods for this project were designed to leverage the existing national wildfire simulation data from Dillon et al. (2023) without further local calibration or modeling work, although one minor edit to the off-the-shelf fuel data was required to calibrate fire occurrence in northern Minnesota. To make the WRC data most useful to communities, we implemented a process to downscale the national burn probability data from their native 270-m cell size to the native 30-m resolution of the nationally available LANDFIRE fuels and vegetation data. Through this process, we also used geospatial smoothing techniques to account for wildfire hazard in parts of communities adjacent to wildland vegetation that may have indirect exposure to wildland fire.

The overall process is defined below.2023T00:00:001. Remove potentially erroneously mapped buildings. To create wildfire exposure zones, we started with the Building Count raster. But because there are some pixels mapped erroneously as buildings (“false positives”) in the Building Count raster, we removed any pixels mapped within USDA or USDOI Wilderness and Roadless areas, while including buildings mapped within 200-m from the inside edge of those boundaries. We also used the following logic to further minimize false positives: Building Count pixels were eliminated if they were greater than 500-m from a road or greater than 2400-m from a housing unit as mapped in the HUCount raster.2023T00:00:00WRC 2.0 Building Count, WRC 2.0 Housing Unit Count2. Restore potential buildings within Census Places. Because Step 1 removed several building pixels that were true buildings, we checked to see if any Census Designated Places (CDPs) have no buildings after that step, and if so, we added them back into the set of filtered building pixels within that CDP. This ensured that we include buildings within communities where roads were sparsely mapped, and Census data does not adequately count population.2023T00:00:00WRC 2.0 Building Count, Census Place boundaries3. Create exposure area around buildings. We buffered filtered buildings by 200-m to approximate an exposure area (approximately 30 acres) surrounding structures where wildfire risk reduction actions may be warranted.2023T00:00:00WRC 2.0 Building Count4. Characterize exposure zones. Within the buffered area surrounding buildings, we reclassified the Exposure Type raster where:
Exposure Type is 0 = Minimal Exposure,
Exposure type is between 0 and 1 = Indirect Exposure, and
Exposure Type is 1 = Direct Exposure.
We then used a 200-m radius moving window majority filter on the classified Exposure Types to define boundaries between exposure zones and represent the influence of adjacent fuels on a pixel’s exposure type. To maintain the spatial precision of the Direct Exposure class, we returned pixels originally in the Direct Exposure class to their Direct Exposure in the final exposure zone raster.2023T00:00:00WRC 2.0 Exposure Type5. Identify building clusters. Though we build an exposure zone around every building across the landscape, the Wildfire Transmission Zone is created only around building clusters. To implement this logic, we create a raster processing mask extending from buildings where either of the following conditions apply:
1. A building is within a 227 m radius of one or more buildings,
OR
2. A building is within a 908 m radius of 16 or more buildings.
Both conditions, when implemented in a raster focal sum operation, generates an area around a building equivalent to 1 building per 40 acres, however the first condition captures buildings that are within 40 acres of another building but in an otherwise sparsely populated area, while the second condition captures buildings near the edges of more densely populated areas. We combined the masks created from these two conditions and selected buildings that fell within the combined area as the starting point from which to build the Wildfire Transmission Zone. We identified the buildings selected with this process as belonging to a “building cluster”, as each one is in a group with other buildings.2023T00:00:006. Create buffer surrounding building clusters. From the building clusters selected in Step 2, we created a 2.4 kilometer (km) buffer to delineate the Wildfire Transmission Zone.2023T00:00:007. Define fuel categories within Wildfire Transmission Zone. Several geoprocessing steps were required to define each of the categories within the Wildfire Transmission Zone (WTZ):
WTZ-Tree is mapped as the area 200 m – 2400 m from building clusters, where LANDFIRE FBFM40 is equal to either a Timber Understory (161, 162, 163, 164, 165), Timber Litter (181, 182, 183, 184, 185, 186, 187, 188, 189), or Slash-Blowdown (201, 202, 203, 204) fuel model.
WTZ-Shrub is mapped as the area 200 m – 2400 m from building clusters, where LANDFIRE FBFM40 is equal to either a Grass-Shrub (121, 122, 123, 124) or Shrub (141, 142, 143, 144, 145, 146, 147, 148, 149) fuel model.
WTZ-Grass is mapped as the area 200 m – 2400 m from building clusters, where LANDFIRE FBFM40 is equal to a Grass fuel model (101, 102, 103, 104, 105, 106, 107, 108, 109).
WTZ-Agriculture is mapped as the area 200 m – 2400 m from building clusters, where LANDFIRE FBFM40 is equal to the non-burnable Agricultural fuel model (93); or where exposure is minimal, FBFM40 is 93, and there are no buildings. The second part of this mapping rule eliminated areas of minimal exposure around buildings surrounded by larger regions of non-burnable agriculture, resulting in a more conservative and intuitive characterization for this Wildfire Transmission Zone category.
WTZ-Non-Vegetated is mapped as the area 200 m – 2400 m from building clusters, where LANDFIRE FBFM40 is equal to a non-burnable Urban, Snow/Ice, or Barren fuel model (91, 92, 99); or where exposure is minimal, FBFM40 is either 91, 92, or 99, there are no buildings, and the majority of pixels within a 200-m radius are non-burnable Agriculture. The second part of this mapping rule is a minor fix that maintains logical consistency by stamping in the WTZ-Non-Vegetated class where Minimal Exposure pixels are surrounded by agriculture.2023T00:00:00LANDFIRE FBFM408. Delineate ancillary zones.Outlying Wildlands is mapped as the area beyond 2400 m from building clusters, where an Exposure Zone is not assigned, or water is not present. Water is mapped as any area where LANDFIRE FBFM40 is water (98).2023T00:00:00LANDFIRE FBFM409. Create final CWiRRZ raster. The final step in creating the CWiRRZ product is to stamp the Exposure Zone raster on top of the Wildfire Transmission Zone and ancillary zones resulting in a raster with the final classes. The raster attribute table includes all information needed to display either the 4 Class or 10 Class CWiRRZ versions:
4-class CWiRRZ – includes the three exposure zones and the entire Wildfire Transmission Zone mapped with a single value.
10-class CWiRRZ – includes the three exposure zones and separate values for each of the fuel categories in the Wildfire Transmission Zone. It also includes the Outlying Wildlands and Water categories.2023T00:00:0010. Produce tabular summaries of wildfire hazard and risk. This publication includes a set of tables that summarize many of the wildfire hazard and risk raster datasets from Scott et al. (2024, https://doi.org/10.2737/RDS-2020-0016-2) and Jaffe et al. (2024, https://doi.org/10.2737/RDS-2020-0060-2) by jurisdictions – states, counties, tribal areas, and communities.
For WRC 1.0 (Scott et. al. 2020), we calculated these summaries as housing unit weighted means within the political boundaries of the different jurisdictions. We summarized risk only where Housing Unit Density is greater than zero, focusing in on the location of homes and the surrounding 200-m radius area used in creating the density raster. For the new summaries in WRC 2.0, we included broader spatial context that captures the hazard characteristics of the surrounding landscape. This was accomplished by summarizing the hazard and risk within three zones defined in the CWiRRZ: the Indirect Exposure Zone, Direct Exposure Zone, and Wildfire Transmission Zone. To capture the full extent of these zones relative to any jurisdiction, we include all area within these three zones that is within 2.4 km of the jurisdictional boundary, such that the wildfire hazard within 2.4 km of all buildings in any jurisdiction is considered in its summary statistics. The metrics reported in the WRC 2.0 tables are also land area based rather than weighted by housing units. This means that averages for this version were calculated with all pixels within the summary area weighted evenly, as opposed to previous calculations that were weighted by the relative housing-unit density at each pixel.
